Window Terms

Daylight Transmittance
Measures the amount of visible light that is transmitted through the glass.

Fenestration
An architectural term referring to the arrangement of windows in a wall. From the Latin word "fenestra" meaning window.

Frame
The enclosure in which window sashes or door panels are mounted.

Glazing
The act or process of fitting a window or door with glass.

Insulated Glass (IG)
A combination of two or more panes of glass with hermetically sealed air space between. This space may be filled with an inert gas, such as argon.

Low-Emissivity (Low-E) Glass
A special type of glass having a microscopically thin metallic layer vacuum deposited into its surface that acts as a thermal mirror. In the summer, Low-E glass lets in visible sunlight while minimizing infrared and ultraviolet solar energy that can increase cooling costs and cause curtains, carpets and furniture to fade. In the winter, Low-E glass helps reduce heating costs by reflecting indoor heat back into the room.

R-Value
Represents a material's resistance to heat flow and its ability to insulate. The higher the R-value, the better insulation performance.

Sash
A single assembly of stiles and rails made into a frame for holding glass.

Stile
The main vertical members of the framework of a sash.

U-Factor (also referred to as U-value)
The rate of heat flow through a glazing system. The lower the value, the better the insulating quality. U-value can be compared to R-value by dividing 1 by the U-value. For example, a U-value of 0.5 equals an R-value of 2.

UV Block
Measures the amount of damaging ultraviolet light that is blocked from being transmitted through the glass.
